DOOR-STOP.

SPECIFICATION forming part of Letters Patent No. 690, d d January 7, 90Application filed March 29, 1901. Serial No. 53 A86. (No model.)

To aZl whom it may concern.-

Be it known that I, WILLIAM V. BLFJHA, a

citizen of the United States, residing at St.

Louis, State of Missouri, have invented certain new and usefulImprovements in Door- Stops, of which the following is a full, clear,and exact description, reference beinghad to the accompanying drawings,forming a part hereof.

My invention has relation to improvements in door-stops; and it consistsin the novel arrangement and combination of parts more fully set forthin the specification and pointed out in the claims.

In the drawings, Figure l is an elevation of the bottom ofadoor, showingmy invention applied thereto. Fig. 2 is a similar view of a window-sash,showing myinveution applied thereto. Fig. 3 is a front elevation of mydevice, showing the stem locked with the lefthand series of teeth of thecasing. Fig. 4 is a similar view showing the stem locked with theright-hand series of teeth. Fig. 5 is a transverse section on line 5 5of Fig. 3. Fig. 6 is a middle vertical section on line 6 6 of Fig. 5,the handle and stem carrying the same being turned, however, out ofengagement with the teeth of the casing, a part of the stem being inelevation; and Fig. '7 is a side elevation of the bottom of thecasing,showing the manner of initiallyinserting the stem and its handleinto the casing.

The object of my invention is to construct a door-stop which may be madeto frictionally engage the floor with variable degrees of pressure,according to the amount of resistance necessary to prevent the movementor swinging of the door after once being opened to a certain position. Y

A further object is to construct a stop which will be simple, durable,cheap, and light and one possessing further and other advantages betterapparent from a detailed description I thereof, which is as follows:

Referring to the drawings, 1 represents an outer cylindrical hollowcasing adapted to be secured to the door by screws passed through thelugs 2 2 2 thereof, the said casing being preferably closed on top andopen at the bottom. The back of the peripheral wall of the casingbetween the lugs 2 2 and the adjacent open end of the casing is cutaway, as at 3, and the front wall of the casing is provided with alongitudinal slot or way 4, through which projects radially theoperating-handle 5 of the reciprocating stem 6, said way having a lowerscalloped or lobed extension 4 to accommodate and limit the handle whenthe latter is in its lowest position. I provided with a longitudinalsocket 7 for the reception of the reduced shank 8 of the rubber bufier8, the base of the stem resting on the shoulder formed between the parts8 and 8. Located directly in line of the base of the handle 5 isatransverse pocket 9 for the reception of a coiled spring 10, which,hearing against the inner surface of the casing, causes the stem toalways hug the inner walls of the casing, and thus holdthe sternfrictionally at any position to which the same may have been shifted inthe casing.

Disposed on each side of the way 4 are series of teeth 11 11,respectively, the one set breaking joint with the opposite set'that isto say, the teeth of one series come opposite the spaces between theteeth of theopposite series. The baseof the handle 5 is provided withalternate series of ribs and spaces 12 12,

which respectively engage the spaces and teeth thus disposed on eachside of the way 4. To look the door in any position to which the samemay have been opened, the operator The stem6is forces the stem downward,so as to cause the buffer 8 to frictionally engage the floor, and thenlocks the stem by turning the same to cause the base of the handle tolock or engage either set of teeth 11 11. If the frictional contactbetween the buffer and floor is found .to beinsufficient after the stemhas been locked by the engagement of the handle and the teeth 11, theoperator may disengage said handle and by forcing the stem farther downward, so as to increase the friction, may bring the ribs 12 of thehandle opposite the spaces between teeth 11' and lock the stem byoffecting an engagement between the coopera tive parts. (See Fig. 4.)The purpose of having the teeth 11 11 break joint is to permit a gradualdepression of the stem where a depression amounting to a full spacebetween any two teeth on one side would be impossible or impractical.

The stem is initially inserted into the casing through the cut-awayportion or gap 3, as

seen in the figures, the handle being made topassthroughthelobeetatthefront. Thestem is then righted-that is to say,tilted parallel to the casing-and inserted into the latter, as isobvious, the spring 10 being compressed to cause it to slip into thecasing with the stem. In practice the door-stop may be manipulated bythe foot, as is obvious, the handle 5 being the part to which the footis applied. Whilespecificallydenominatedherein as a door-stop, it isapparent that it may be used as a sash-lock, as obvious from theillustration in Fig. 2.

It is apparent, of course, that I may alter the present construction inminor details without departing from the spirit of my invention.

Having described my invention, what I claim is-,-

1. Adoor-stop comprising an outer casing, a longitudinal peripheral wayformed in the walls thereof, a sliding stem mounted and rotatable withinthe casing, teeth disposed on each side of the way, those on one sidebreaking joint with those on the opposite side, a handle carried by thestem, the handle having a base adapted to lock with either series ofteeth when turned to one of its extreme positions, substantially as setforth.

socket formed at the inner end of the stem,

a spring confined in the socket and bearing against the adjacent wall ofthe casing, a handle secured to the stem and located diametricallyopposite the transverse socket, a rear terminal peripheral gap beingformed in the wall of the casing for the initial reception of the handleand stem, teeth disposed on each side of the way, those on the one sidebeing opposite the spaces between the teeth on the opposite side, andsuitable engaging ribs and spaces at the base of the handle forcooperating with the spaces and teeth of the casing, the parts operatingsubstantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
